Indoor Unit Size(s) Mini split systems can have one or more indoor units connected to a single outdoor unit. Indoor Unit Size(s) specifies what indoor unit sizes are used in a system. For example (09 + 12) means the system includes a 9k BTU unit and a 12k BTU unit.

09 + 12 + 12 + 18

LG's devotion to providing efficient ductless solutions can be seen across the Multi F line. This wall mounted designer ductless heat pump system pairs a powerful LMU540HV outdoor condenser with four wall mounted indoor units from LG's Art Cool Mirror line. With a sleek mirrored finish, Art Cool Mirror units look right at home on the wall of modern homes. The stunning design may be the first thing people notice, but it's hardly the only benefit to these indoor units, their functionality is just as robust as LG's other wall mounted units. With options for automated comfort and a convenient wireless remote, this system has a lot to offer to any home.

Low Ambient OperationsCold temperatures can't slow the Multi F line of outdoor condensers down. This outdoor unit supports cooling operations down to 14 degrees Fahrenheit and heating operations down to -4 degrees Fahrenheit. There is also a defrost feature, which removes frost from the condenser coil in frigid conditions.

Quiet DesignThanks to a brushless direct current fan motors, both the outdoor and indoor units in this system produce less mechanical and electrical noise, allowing them to provide comfort that doesn't disrupt your home. A twin rotary compressor in the outdoor unit also limits vibration noise and the indoor units feature a cross flow fan design that further reduces sound levels by rectricting the surface pressure of airflow.

Air Flow OptionsLG's wall mounted multi-zone indoor units give you two options for automating air flow. In swing mode, a unit will rotate through all four air flow directions to ensure consistent comfort in every corner of your room. With the Chaos Wind feature, which cycles both air flow direction and fan speed, you can enjoy a natural circulation pattern in the comfort of your home.

Sleep ModeWith the sleep mode and timer functions, you can set the indoor units to save energy at night. Sleep mode will incrementally adjust temperatures for an hour before the timer function automatically deactivates the units. A second timer can bet set to activate the unit in the morning to ensure that your home is the perfect temperature when you wake up.

Improved Air QualityThe Art Cool Mirror indoor units use a dual filtration system to keep your air clean. A washable anti-fungal filter is the first line of defense against dust and bacteria. This filter is backed up by a high air flow 3M Micro Protection Filter that captures microscopic irritants for pristine air quality.

DehumidifyLG's multi-zone indoor units include a dehumidifying operation mode. In this mode, the units' internal sensors monitor temperature and modify the set point and fan speed to remove moisture from the air.

Hot StartWhen the hot start function is enabled on a mini split indoor unit, the fan will not engage until the outdoor condenser has had the opportunity to warm the indoor coil. This prevents the unit from blowing cold air during heating operations.

2 Questions Answered

Q: What is the maximum length of the tubing from the outside unit to the inside unit?by Anthony from New Jersey on August 15, 2016

A: This condenser requires the use of one or more branch boxes. There is a maximum piping to both branch boxes of 180.4 ft. The maximum length to any one indoor unit from a branch box is 49.2 ft. The maximum total line set length is 475.7 feet.

Q: Can the LG system deliver heat down to 5 degrees? If so, are the BTU ratings listed the same at this temp?by Andrew S. from Massachusetts on July 24, 2016

A: LG outdoor units do not shut down based on outdoor temperature*. They will deliver heat at 5 degrees, and lower. However, their output will decrease as temperature drops toward freezing and below. For specific details on capacities at different outdoor temperatures, you can reference the Engineering Manual. If you need any help interpreting the manual, feel free to email or call us.

*The units will shut down if operating pressures in the systems are unsafe. Once pressures return to safe levels, the units will resume operation. by Chris, Product Expert
